Hennessey may have just released the Mammoth 1000 6×6, a $450,000 Hellephant-swapped TRX. However, that’s not your only choice for a 6×6 Dodge pickup because a shop called Force Motorsport unveiled their own TRX 6×6, fit for Florida swamps and high streets. It doesn’t have a name, but the choice of Vossen wheels makes it stand out.
Andrei and I have been following Vossen wheels for the past 11 years. This is one of their latest alloy designs, the HF6-4 which is popular in the sports truck scene. It’s got a modern multi-spoke look that gives the TRX a sports car appearance instead of going with the rugged/beadlock off-roader path. It’s fitting, considering the 6×6 conversion has massive street appeal.
This sating black optional finish matches the six Vossen wheels to the color of the black plastic cladding. These are 22×12-inch alloys and are wrapped with 37-inch rubbers. So the tires are about as tall as a normal TRX, but wider and fitted with larger alloys (normally 18s).
Tower of power, tires to devour
The 6×6 conversion is exactly what you’d expect from an extended truck. The rear end sports an extended chassis and bed to accommodate the extra axle. The suspension seems set up quite differently from what Hennessey has done, at least as far as the shocks are concerned.
Force Motorsport is the Florida expert in this field and has built many of the 6×6 Jeep Gladiators you may have seen. They’ve also modified a 2022 Toyota Tundra already, though the bed isn’t ready yet.
Again, Hennessey does offer a 1000 horsepower conversion for the TRX. But I don’t think you need it in this case. The Hellcat engine is already the most powerful ever fitted to a pickup truck, and there are numerous mods that you can do if 702 horsepower somehow isn’t enough.
$450,000 is the minimum cost of a Hennessey Mammoth 6×6. We don’t know the price of this conversion, but it’s got to be around $300,000. Jeeps are cheaper to modify into this configuration, but the TRX continues to be in high demand, and a nice one costs way more than the stated MSRP.
